Inflammation (infection) of postprocedural bleb.Also known as Postprocedural blebitis.

Excludes1: filtering (vitreous) bleb after glaucoma surgery status (Z98.83). Do not use H59.4 with codes for mechanical complications of implanted devices (T85.2, T85.3), pseudophakia (Z96.1), or secondary cataracts (H26.4-).

Medical necessity is established by the presence of inflammation or infection at the site of the postprocedural bleb, potentially compromising vision or causing significant discomfort.

Inflammation (infection) of postprocedural bleb. Postprocedural blebitis

Example 1: A patient develops a red, painful, and swollen bleb on their eye a week after glaucoma surgery. The ophthalmologist diagnoses postprocedural blebitis., Following a trabeculectomy, a patient presents with discharge and tenderness at the bleb site. Cultures confirm an infection of the postprocedural bleb., A patient who underwent surgery for a detached retina experiences inflammation in the bleb created during the procedure. This inflammation, while not infected, causes discomfort and requires treatment.

Documentation should include the type of eye surgery performed, the location and appearance of the bleb, presence of inflammation or infection (including any culture results), and associated symptoms.

** This code specifically refers to inflammation or infection of a bleb formed after a surgical procedure on the eye.It should not be confused with bleb formation or complications related to other implanted devices or conditions like pseudophakia or secondary cataracts.For accurate and comprehensive coding, additional external cause codes (e.g., for infections) may be necessary.
